Observational constraints on cosmological superstrings

TL;DR

This paper explores observational methods to identify and differentiate cosmological superstrings predicted by superstring theory, establishing constraints on their properties based on current data.

Contribution

It introduces new observational constraints on superstring tension and deficit angles within a brane-world scenario, aiding in distinguishing superstring types.

Findings

Lower limit on superstring tension derived

Constraints on deficit angles established

Potential observational signatures identified

Abstract

From theoretical point of view and not being in contradiction with current observational data, the cosmic strings should have fundamentally different origin and are characterized by wide range of energies. The paper is devoted to search for possible cosmological observational tests on superstring theory, among them to identification of observational characteristics to distinguish between cosmological superstring of different types. In the brane-world scenario with an assumption of creation of cosmological superstrings it was obtained the lower limit on the superstring tension as function of deficit angle.
